JDK | Java Development Kit

Java Development Kit (JDK)

The Java Development Kit is a software development environment used to create Java applications. The JDK includes JRE (Java Runtime Environment), an interpreter (java), a compiler (javac), an archiver, a documentation generator, and other tools needed for java application development.

JDK

Oracle Corporation is releasing the platform in the form of a binary product aimed at Java developers on Solaris, Linux, Windows or macOS.

JDK 1

JDK is the implementation of any one of the following Java Platforms, released by Oracle corporation:

  • Standard Edition Java Platform
  • Enterprise Edition Java Platform
  • Micro Edition Java Platform

Components integrated with JDK are:

appletviewer The tool can be used to execute and debug Java applets without a web browser.
extcheck It is a component that detects JAR file conflicts.
java It is the loader for Java applications.This tool is an interpreter and can translate the class files generated by the javac compiler. After the introduction of this utility, a single launcher is used for both development and deployment.
javac It is the Java compiler, which converts source code into Java bytecode.  
javadoc It is a documentation generator, which automatically generates documentation from source code comments.
jar It is the archiver, which packages related class libraries into a single JAR file.
apt: It is an annotation –processing tool.
idlj It is the acronym for the IDL-to-Java compiler. This utility of JDK generates Java bindings from a given Java IDL file.
jabswitch It is the Java Access bridge. It opened assistive technologies on Microsoft Windows systems.
javafxpackager A tool to package and sign JavaFX application
jarsigner A jar signing and verification tool.
javah It is a C header and stub generator which is used to write native methods.
javap A class file disassembler.
javaws It is a Java Web Start launcher that can be used by the JNLP application.
jConsole Java Monitoring and Management Console
jdb   It is a debugger that is used to test and debug the programs.
jhat Acronym for Java Heap Analysis Tool, it is an experimental utility not yet published publicly.
jinfo The utility gets configuration information from a running Java process or crashed dump but it is an experimental component of JDK.
jmap Oracle-jmap MemoryMap The components return the memory map and can print the shared object memory map or heap memory detail of a given process/core dump. (experimental)
jmc Java Mission Control, allows Java administrators and developers to gather detailed low level information about how the Java Virtual Machine (JVM) and the Java application are behaving.
jps Java Virtual Machine Process Status Tool which lists the instrumented HotSpot Java Virtual Machines (JVMs) on the target system. (experimental)
jrunscript Java command-line script shell. That enables the programmer to access the operating system’s services.
jshell The new jshell introduced in java 9.
jstack The component that prints Java Stack traces (a report of the active stack frames at a certain point of time when the program being executed) of Java threads (experimental)
jstat Java Virtual Machine statistics monitoring tool (experimental)
jstatd jstat daemon (experimental)
Keytool A tool for manipulating the keystore (a repository of security certificates- either authorization certificates or public key certificates).
Pack200  JAR compression tool which can be used to reduce the size of the jar file.
policytool It is the policy creation and management tool, which determines the policy for a Java runtime and specify that which permissions are available for code from various sources.
VisualVM  It is a visual tool that integrates several Command-Line JDK tools, lightweight performance and memory profiling capabilities.
wsimport It generates portable JAX-WS (Java API for XML Web services) artifacts for invoking a web service.
xjc The component is part of the Java API for XML Binding (JAXB) API which accepts an XML schema and generates Java classes.
